Marcel Audiffren was a French priest, physicist, and inventor who promoted the residential refrigerator. He served as abbot of his Cistercian monastery, and originally designed a hand-cranked device for cooling liquid, such as wine, for his monks. His machine was patented in France in 1894. The patent stated "It can be cranked by hand or driven by an engine."[http://www.refresearch.com/m-audiffren.html Refrigeration Research Website] {{webarchive|url=https://web.archive.org/web/20070222005055/http://www.refresearch.com/m-audiffren.html |date=2007-02-22 }}

European-manufactured refrigerators based on his designs were first sold in the U.S. in 1903.{{citation needed|date=February 2020}} He received U.S. Patents #551,107 (in 1895) and #898,400 (in 1908, with Albert Sigrun).

Machines based on Audiffren's sulfur dioxide process were manufactured by General Electric in Fort Wayne, Indiana and marketed by the Johns-Manville company. The first unit was sold in 1911. Audiffren machines were expensive, selling for about $1,000—about twice as much as an automobile cost at the time.{{citation needed|date=February 2020}}
